Description Gérard Milmeister 2011-02-09 21:40:54 UTC
Description of problem:
The keyboard (PS/2, not USB) will sooner or later get stuck.
The most common symptom is the continuous repeating of one the
last pressed keys (It also happened that no input at all comes any
more from the keyboard). There is no way to stop it (neither with the
keyboard connected nor unconnected). The USB mouse is unaffected,
and the system is not hung (remote login possible). No system log
entry. Only reboot gets keyboard working again.
This is filed under kernel, since I suspect the keyboard controller
being involved.
I also tried the following things (as found by googling),
without success:
1. stop irqbalance
2. add i8042.reset=1 i8042.nopnp=1 i8042.noaux=1 i8042.nomux=1
to kernel parameters.

The mainboard is an Asus P7P55D-E, with most features disabled,
and a 4-core Intel i7.


Version-Release number of selected component (if applicable):
kernel-2.6.35.10-74.fc14.x86_64

How reproducible:
Not deterministic.

Comment 1 Chuck Ebbert 2011-02-10 19:29:21 UTC
You should be able to recover by switching to a console (ctrl-alt-f2) and then back to the graphical session (ctrl-alt-f1).

What kind of keyboard is attached?

Comment 2 Gérard Milmeister 2011-02-12 12:25:48 UTC
The keyboard does not respond any more at all.
The keyboard is a PS/2 UNICOMP.

However I have found the following:
I login remotely, dmesg has the line
  ...drivers/input/serio/i8042.c: Interrupt 1, without any data...
which is a hint that the kernel driver is involved.
Then I do the following as root:
  echo -n reconnect > /sys/devices/platform/i8042/serio0/drvctl
and the keyboard is working as before.

As a workaround I can run a script that regularly performs
the reconnection, but this should of course only by a
temporary fix.

Comment 3 Chad Sawatzky 2011-02-15 08:01:27 UTC
I'm experiencing the same problem.  Using the reconnect command via remote login as described in previous comment has worked in restoring a working keyboard.

I've noticed it happen twice tonight.  I applied the kernel-2.6.35.11-83.fc14.x86_64 two two days ago.

Comment 4 Fedora End Of Life 2012-08-16 13:45:08 UTC
This message is a notice that Fedora 14 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 14. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen 
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 14 reached end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
